门球是一项多人参加的用槌击打小球过小门的竞技娱乐性体育项目，特别受到中老年人的喜爱。

门球一般在长20-25米，宽15-20米的场地中进行，参与者分为两队，一队一般为5人。比赛采取记分形式判断胜负。门球场地中有三个门一个柱，每位球手的球过一门得1分，三门都通过后球撞柱可得2分。每场比赛一般为30分钟，比赛结束时得分较高的一方获胜。

门球起源于日本，由铃木荣治（稍后改名铃木和伸）于1947年发明，他借鉴了英国传统槌球（Croquet）运动（起源于14世纪），当时是为了给儿童提供一种娱乐游戏方式，但没有被儿童接受，反而被老年人所喜爱。1983年门球被介绍到中国，同样受到中老年人的欢迎。目前门球在世界上有超过1,000万的爱好者。

Gateball(Japanese:ゲートボール,Hepburn:gētobōru) is a mallet team sport similar to croquet. It is a fast-paced, non-contact, highly strategic team game, which can be played by anyone regardless of age or gender.

Gateball is played on a rectangular court 20 meters long and 15 meters wide. Each court has three gates and a goal pole. The game is played by two teams (red and white) of up to five players. Each player has a numbered ball corresponding to their playing order. The odd-numbered balls are red and the even-numbered balls are white. Teams score one point for each ball hit through a gate and two points for hitting the goal pole, in accordance with the rules. A game of gateball lasts for thirty minutes and the winner is the team with the most points at the end of the game.
